The back screen of Gopro9 is not displayed.

First: the computer system is aging, that is, the system file version is too low. For the compatibility card machine caused by the lack of compatibility and support of new software, the system can be redone to solve it.

Second, there are too many background running projects and too many startup projects in the computer, which leads to insufficient memory. Use optimization software to kill useless background running programs and close startup projects.

Third: the computer's physical memory is insufficient, and the memory bar collapses due to aging or voltage problems, so the memory can be replaced.

Fourth: the CPU process is overloaded, which exceeds the maximum capacity of the CPU. Data processing failure leads to system crash, system redo, or opening process manager to close useless processes.

Fifth: the weather temperature is high in summer, and the exhaust inside the machine is not smooth. High utilization rate causes cpu temperature to rise and crash. You can use auxiliary cooling tools to dissipate heat, check whether the silicone at the CPU is good, and apply silicone. Judge for yourself and deal with it relatively.
